Abstract: END POINT DETECTION METHOD          Abstract The clearing point of photoresist development is detected automatically by illuminating the developing photoresist surface with intense monochromatic light.          Interfering reflection from the resist-substrate interface and the fast eroding and slow eroding resist surfaces produces fast and slow oscillatory signals.  These signals are processed to produce a logical output indicative of the cessation of the fast oscillations in the presence of the continuing slow oscillations signaling the clearing point of development.

Abstract: Abstract of the Disclosure In a print hammer mechanism in which a thin, flat hammer spring is mounted at a fixed end thereof to a magnetic structure which includes a permanent magnet and a pole piece having a pole tip facing the opposite free end of the hammer spring on a side of the hammer spring opposite an impact printing tip, a pivot fulcrum is formed by an impact arrangement which faces an intermediate portion of the hammer spring between the fixed and free ends thereof.  The permanent magnet normally pulls the hammer spring into a retract position in which the spring impacts and resides against the impact structure with the free end of the spring forming an air gap with the pole tip.  Energization of a coil surrounding the pole piece releases the hammer spring from the retract position, enabling the spring to return toward a neutral position and then impact a printable medium such as a print paper-ink ribbon combination, following which the magnetic attraction of the permanent magnet returns the hammer spring to the retract position in which it strikes the impact structure and remains in the retract position pending the next energization of the coil.  The location of the impact arrangement is such as to greatly minimize wear at its interface with the hammer spring while at the same time enhacing the release characteristics of the hammer spring.          In a preferred embodiment the impact structure is formed by a secondary pole piece extending in parallel, spaced-apart relation along a portion of the length of the hammer spring from the fixed end thereof and termina-ting in a pole tip covered with a thin layer of Kapton.

Abstract: CHEMICAL HEAT AMPLIFICATION IN THERMAL         TRANSFER PRINTING              ABSTRACT            Chemical heat amplification is provided in thermal transfer printing, wherein some of the heat necessary for melting and transferring ink from a solid fusible layer in a ribbon to a receiving medium is provided by an exothermic reaction.  This chemical reaction is due to an exothermic material that is located in the ink layer, or in another layer of the ink bearing ribbon.  The exothermic reaction reduces the amount of the input power which must be applied either electrically or with electromagnetic waves.  Examples of suitable exothermic materials are those which will provide heat within the operative temperature range of the ink, and include nonaromatic azo compounds,  peroxides, and strained valence compounds, such as monomers, dimers, trimers  of the type which change their chemical bonding when they decompose to either a valence isomer or break into a number of molecular species.

Granted: 1986-08-12
Abstract: A  b  s  t  r  a  c  t This invention relates to a spark ignition air-compressing internal combustion engine having a combustion chamber in the shape of a solid of re-volution with a constricted transfer opening in the piston where the injection nozzle is situated in the cylinder head near the combustion chamber edge and the ignition device opposite the injection nozzle penetrates into the combustion chamber at the top dead centre position of the piston and where mixture formation is predominantly by deposition of the fuel on the wall of the combustion chamber. In such an internal combustion engine, the widely variable flow near the combustion chamber wall is proposed to be equalized and absolutely reliable ignition and optimum combustion ensured in all operating ranges, although the length of the electrodes of the ignition device is drastically shortened with a view to mini-mizing wear. According to the invention this is essentially achieved by the use of a special shape and proportioning of the combustion chamber (Fig. 1).

Abstract: METHOD AND APPARATUS FOR DETECTING THE ONSET     OF MELTING IN A RESISTANCE SPOT WELD          Abstract of the Disclosure During a weld period the weld parameters are monitored and data representing the weld resistance curve and the power curve are acquired and stored for analysis by a suitably programmed computer. The derivative of R, R is calculated and stored and the function is divided by power P to obtain R/P.  The resistance curve is searched to obtain the maximum value Rm which occurs during the heating phase and the function R/P is searched prior to the time of Rm to find the maximum of that curve representing the highest rate of resistance increase.  Then the R/P curve is searched subsequent to its maximum to deter-mine when the function reaches a specified percentage of the maximum.  That value occurs at the knee of the resistance curve and approximates the onset of melting in the weld.           A prediction of whether a weld is a nugget or a sticker is made by calculating the ratio of weld energy after the onset of melting to the total weld energy, the ratio of the resistance drop after the resistance peak to the peak resistance, and then a weighted sum of the energy ratio and resistance drop ratio.           An edge weld geometry is detected by calcu-lating from the resistance and power curves the weld energy during the period of expulsion, if any, divided by the cumulative energy between the onset of melting and the end of expulsion, a measure of expul-sion intensity based on the maximum degree of resis-tance inflection, and then a weighted sum of the energy value and the inflection value.

Abstract: "SEED HARVESTER" ABSTRACT OF THE DISCLOSURE A seed harvester is provided for harvesting seeds from a standing crop without cutting the crop. The harvester is particularly de-signed for harvesting grass seed. The harvester includes a header assembly for stripping from the crop, and a seed separator for drawing the seeds from the header assembly in an air stream and for separating the seeds from the air stream. The header assembly includes a frame assembly having a transverse inlet which communicates with the seed separator. An endless revolving stripping surface is mounted across this transverse opening to contact the seed heads of the crop and strip the; mature seeds from the crop. A rotating reel is mounted to rotate parallel to, and above and forwardly of, the seed stripping surface. On rotation, the reel guides the crop into contact with the seed stripping surface and holds it there for a time to permit the seed stripping surface to remove mature seeds from the crop. The seed separator includes-a duct, curved between its ends. The duct inlet communicates with the transverse inlet of the header assembly. A blower is provided at the duct outlet to draw seeds in an air stream, from the header assembly and through the duct. Baffles are provided across the curved duct section which, together with the curve in the duct, cause the seeds to move outwardly toward the outer wall of the curved duct section. This achieves partial separation of the seeds from the air stream. To achieve the remainder of the separation, the seed separator includes a seed with-drawal duct in the outer wall of the curved duct section, and a sealed con-tainer at the end of the seed withdrawal duct. Air is drawn through the container and the seed withdrawal duct, preferably by the blower, to carry the seeds in an air stream into the container.
